Index Law, Multiplying with the same base, Index and Expanded Form

Description:

This resource is a whole lesson/lesson plan for Year 8 Maths teachers who teach Index Numbers (Index Laws), specifically, multiplying with the same base, index and expanded form and prime factors of a composite number. It will help you teach a smooth lesson even if you do not have a strong mathematical background. Just run the PowerPoint.

Learning Objectives:

By the end of the lesson, students should be able to:

• Write in index form
• Write in factor (expanded) form
• Multiply numbers in index form with the same base
• Write a composite number as a product of prime numbers

Links to curricula:
• Use index notation with numbers to establish the index laws with positive integral indices and the zero index (ACMNA182)

The lesson follows the explicit teaching method: I DO, YOU DO, WE DO.
There is a Lesson Focus & Success Criteria slide with learning objectives.
At the end of the PowerPoint file, there is a homework slide. The suggested pages and the question numbers are for the book Maths Quest 8, published by Jacaranda.
